See first of all I'll like to say to you that.. Coaching is just a push in your journey, the basic requirement is that you must be ready for facing the challenge, you must be devoted and dedicated towards your studies. 

I'll enlist some of the good coaching classes as per the students reviews in bhimavaram. 

Raise Institute is a renowned coaching class there for neet which provides smart teachers and teaching for all the 3 subjects. Edukad Kota is also a good coaching class. Even you can try for Ambition Groups. Whichever classes fits in your budget you can go for that and just a suggestion to you personally... That stay dedicated towards studies right from the beginning because that is the most insane feeling when you clear this exam. 

Best wishes. Thank you.
